occurring July 17. The third instar required five days 
moulting occurring July 22. The female oviposited on 
species of Tradescantia and on Lippia. 
The former was probably chosen by the female in error 
due to its proximity to the food plant. Larvae would not 
feed on it. 
Eumaeus atala Poey 
The larva and chrysalis of this species have been described 
in part by Scudder (1875). The following account deals 
primarily with the arrangement of setae and body colors, 
aspects not previously considered. 
Last Instar. Head height 2 mm. ; head width 2.5 mm. 
Head yellowish. Few minute scattered hairs. The distri- 
bution of these is shown in Plate V Figure 4. On the head 
the primary and secondary setae are indistinguishable. 
They are of little diagnostic value since they vary so greatly 
in number and position. Plate VI Figures 9 and 10 illus- 
trate the marked variation in the distribution of these head 
setae in different specimens of this species. The apex of the 
head is deeply indented. Surface smooth. Body 20 mm. 
long. General color brilliant crimson. First and last seg- 
ments yellowish. Legs, prolegs, and para-dorsal spines 
yellow. Spiracles light brown, spherical. Para-dorsal row 
of fleshy tubercles on every segment. Each bears three to 
five stiff black spines. The para-dorsal tubercles on the first 
and last body segments are not distinct. Body covered with 
much short brown secondary hair. A substigmatal row of 
fleshy protuberances crimson in color. Prothoracic seg- 
ment enlarged. Crochets triordinal, numbering approxi- 
mately thirty-three. Arranged in one interrupted band with 
a spatulate fleshy lobe arising near the interruption. 
Chrysalis. Length 15 mm. General color sienna. Scat- 
tered brownish spots.
